“Do you realise our DNA is 98.5% identical?”
These are the words in an advertisement for the first-class stamp (top
right) in a new series called “The secret of life,” released
by Royal Mail (UK). The stamps commemorate the 50th anniversary
of Watson and Crick’s discovery of DNA’s structure and recent
advances in human genome research.

Posters advertising the stamps are plastered all
over Post Offices in the UK—even AiG staff from the US were bombarded with
this message during a recent speaking trip
there [see Busy in Britain].

Cartoonist Peter Brookes of the London Times
drew the pictures, using humor to make his message clear. For his first-class
stamp, he chose to show the link between apes and scientists, and label it
“comparative genetics.” Obviously, this implies that one of the most significant
outcomes of DNA research is its evidence for human evolution.

Another stamp in the collection promotes a similar
message. According to Royal Mail’s promotion on its Web site, the stamp titled
“The End of the Beginning,” which shows scientists completing a jigsaw puzzle,
“signifies that the discoveries made so far, and the mapping that continues,
present us with the method of finding the beginning of life (emphasis
added).”1

Discrediting “the god hypothesis”

Indeed, the title of the whole series, “The secret
of life,” is taken from a famous quote by one of the discoverers of DNA’s
double-helix structure, Francis Crick, who saw it as a confirmation of evolution
and a death knell to religion. (Crick announced fifty years ago at a pub
in Cambridge: “We have discovered the secret of life.’)

An outspoken atheist, Crick was motivated by a bigger
prize than the Nobel laureate. He openly admits that he has devoted his life
to discrediting what he considers to be the two most powerful “design” arguments
for God: chemicals can’t explain life and chemical processes can’t explain
human consciousness. As he explained to the London Telegraph:

“I went into science because
of these religious reasons, there's no doubt about that. I asked myself what
were the two things that appear inexplicable and are used to support religious
beliefs: the difference between living and nonliving things, and the phenomenon
of consciousness.”2

Although Crick’s work with DNA is more widely known
than his work on the human brain,3 both lines of research were intended to confirm the same conclusion:
“The god hypothesis is rather discredited.”

Of course, nobody can deny the significance of Crick’s
discovery. In 1953, it was still a deep mystery how heredity worked—how living
things reproduced and transmitted their characteristics. The discovery of
DNA’s structure truly revolutionized biology, and led to the mammoth Human
Genome Project (see Genome Mania—Deciphering the human genome: what does it mean … ). The potential
medical benefits from this project are truly exciting, as the stamp “Medical
futures” emphasizes.

On the other hand, the belief that DNA research
improves our understanding of human origins is a farce. Although the field
of comparative genetics has revealed some interesting facts about the similarities
(and differences) of DNA among different species, it says nothing about the
origin of our DNA or the historical relationship between species.

Just because we share half our DNA with bananas,
doesn’t mean we’re “half a banana.”4 Similarly, if there were 98% genetic similarity between humans
and chimps wouldn’t mean that we were 98% chimps.5 But in fact, recent evidence indicates
that the genetic similarity is significantly less than this.

The real lesson of DNA

The real, unheralded lesson of the past 50 years
of DNA research is the evidence of an amazing Designer, who made all things,
including a marvelously complex, efficient “information system” for encoding
life—something that could not have arisen by mere time and chance.

DNA obeys the laws of physics and chemistry, but
it carries something much more than that, something which is not known to
arise from mere physics and chemistry—information.6 A
car functions according to the physical laws—i.e. there is nothing “spooky”
that makes cars operate. But the physical laws plus time plus chance could
never build a car. The missing ingredient is information—the intelligent
purposive design impressed onto those raw materials.

In the same way, DNA carries the blueprint for living
things, which is transmitted from one generation to the next, like a series
of robots programmed to pass on their programs to other robots. But since
observational science has never revealed any natural process that can create
information, i.e. “write the program,” the most logical conclusion is that
the programs themselves, i.e. the information in the original created kinds,
arose from an intelligent mind—the same way programs arise today.

But don’t expect such an obvious
scientific conclusion from a world steeped in evolutionary rebellion against
its Maker.

The second
half of Crick’s life focused on brain research, as he explained in his 1994
book The Astonishing Hypothesis: The Scientific Search for the Soul,
which claimed, “Your joys and your sorrows, your memories and your ambitions,
your sense of personal identity and free will, are in fact no more that the
behavior of a vast assembly of nerve cells and their associated molecules.”
